Elastic Energy Driven Polymerization [PDF]
Biophysical Journal, 2009 We present a molecular system where polymerization is controlled externally by tuning the elastic energy of the monomers. The elastic energy, provided by a DNA molecular spring, destabilizes the monomer state through a process analogous to domain swapping. This energy can be large (of approximately 10 kT) and thus drive polymerization at relatively low

Minimizing Configurations for Elastic Surface Energies with Elastic Boundaries [PDF]
Journal of Nonlinear Science, 2021 We study critical surfaces for a surface energy which contains the squared $L^2$ norm of the difference of the mean curvature $H$ and the spontaneous curvature $c_o$, coupled to the elastic energy of the boundary curve. We investigate the existence of equilibria with $H\equiv -c_o$. When $c_o \ge 0$ we characterize those cases where the infimum of this

A regularized gradient flow for the p-elastic energy [PDF]
Advances in Nonlinear Analysis, 2021 We prove long-time existence for the negative L 2 {L}^{2} -gradient flow of the p-elastic energy, p ≥ 2 p\ge 2 , with an additive positive multiple of the length of the curve. To achieve this result, we regularize the energy by cutting off the degeneracy

Elastic energy of multi-component solid solutions and strain origins of phase stability in high-entropy alloys [PDF]
, 2021 The elastic energy of mixing for multi-component solid solutions is derived by generalizing Eshelby's sphere-in-hole model for binary alloys. By surveying the dependence of the elastic energy on chemical composition and lattice misfit, we propose a ...

Topological Rainbow Trapping for Elastic Energy Harvesting in Graded Su-Schrieffer-Heeger Systems [PDF]
Physical Review Applied, 2020 We amalgamate two fundamental designs from distinct areas of wave control in physics, and place them in the setting of elasticity. Graded elastic metasurfaces, so-called metawedges, are combined with the now classical Su-Schrieffer-Heeger (SSH) model ...

Expression for the granular elastic energy [PDF]
Physical Review E, 2012 Granular Solid Hydrodynamics (GSH) is a broad-ranged continual mechanical description of granular media capable of accounting for static stress distributions, yield phenomena, propagation and damping of elastic waves, the critical state, shear band, and fast dense flow.

The Anticipation of Gravity in Human Ballistic Movement
Frontiers in Physiology, 2021 Stretch-shortening type actions are characterized by lengthening of the pre-activated muscle-tendon unit (MTU) in the eccentric phase immediately followed by muscle shortening.

ON THE REPRESENTATION OF ENERGY AND MOMENTUM IN ELASTICITY [PDF]
Mathematical Models and Methods in Applied Sciences, 2000 In order to clarify common assumptions on the form of energy and momentum in elasticity, a generalized conservation format is proposed for finite elasticity, in which total energy and momentum are not specified a priori. Velocity, stress, and total energy are assumed to depend constitutively on deformation gradient and momentum in a manner restricted ...
